Quote: One’s appearance bespeaks dignity corresponding to the depth of his character. One’s concentrated effort, serene attitude, courteous disposition, thoroughly polite bearing, piercing look – each of these reveals dignities. Such outward appearance, in short, comes from constant attentiveness and seriousness. — Yamamoto Tsunetomo (1659–1719) Japanese Samurai & Buddhist priest
Comment: A boy who is naturally (genetically) debonair is not aware he is special even though his mates treat him with a little more respect or envy. He can grow up and feel privileged or he can treat everyone else with the same deference he enjoys.
